"The Apollo 10 patch was based more on the mechanics and goals
of the mission than the philosophy of the space program or the astronauts
flying this mission... The patch was basically designed by the crew,
primarily Young and Cernan, with a great deal of help from the artists
at North American Rockwell. North American and Grumman eventually
were the producers and primary suppliers of the patch".

Stafford and Cernan flew together on Gemini
9A, and the patch for that flight is strikingly similar to this
one. Both patches are in the shape of a shield, and the dominent
design elements are the spacecraft and the mission objectives, with
the mission number of the flight represented as a large Roman numeral
in the middle of the design. In the case of the Apollo 10 patch,
the word "Apollo" and the crew names were added; except
for that, the verbal description applies to both patches.

The creator of this patch was unknown until May 2008, when Ed Hengeveld and Noah Bradley identified Allen Stevens of North American Rockwell as the artist.

This embroidered patch is the version the crew wore for
their "formal" portrait (see detail below). It
was supplied to the crew by Grumman, the builder of the
LM. 104mm w × 104mm h

The Lion Brothers embroidered Apollo 10 patch differs markedly
from the patch at the left, though it follows the artwork
more closely (note the attitude and shape of the LM ascent
stage, for example).

An embroidered variation of unknown origin. Matches the
artwork very nicely.

[ap10-em4]
Embroidered AB Emblem version of the Apollo 10 patch. The
shape of the shield is more triangular than the artwork,
and the typography used for the crew names is Eurostile
rather than Eurostile Extended as in the artwork.
